Syncfusion.Xamarin.SfPdfViewer causes iOS app to crash on closing, other platforms are ok

[YR]

Hi there, I wonder if someone can suggest anything? Non shell app, with latest components, after release to the store with linked SDKs only fails on iOS, regardless of size - any pdf file causes app to crash. The page is very simple design, even without using below still crashes the same. Please help! :)

        protected override void OnAppearing()

        {

            base.OnAppearing();

            if (ViewModel.PdfDocumentStream != null)

                pdfViewerControl?.LoadDocument(ViewModel.PdfDocumentStream);

        }

        protected override void OnDisappearing()

        {

            base.OnDisappearing();

            try

            {

                ViewModel.PdfDocumentStream?.Close();

                ViewModel.PdfDocumentStream?.Dispose();

                pdfViewerControl?.Unload();

                pdfViewerControl?.Dispose();

            }

            catch { }

        }
